On the world of Allden, life...has become cruel. The encroaching desert swallows whole cities. The anarchists and the lawless wander the wastes. Nothing is sacred and no one is truly safe. For this reason, the Nomads were created. Fantastic wooden sailing ships and their crews that ply the currents above the barren lands, bringing order from chaos, hope from despair... Yet even they are powerless to stop the threat that looms before them all...a portent of doom that will shake the very foundation of the world and its people... The sun is collapsing. Time is running out. Who, if any, will survive?
